[Samba] Multiple Domains?

> Downloading the latest now.

Okay, now for the scary part.  This machine is live, and in use all day every
day.  Anything I should know about upgrading from 2.0.7 to 2.2.5?

I always like having a backup plan in place before something major like this.

Does SAMBA rely on anything outside it's own directory?  I want to make a
couple of tarballs so I can "go back" if needed.

TIA
